Don't use Venice's method, that one sucks very hard.
Use ZCMD/DCMD and SSCANF2. Example code:
ZCMD:

pawn Код:

CMD:irc(playerid, params[])
{
    new message[128], pName[24];
    GetPlayerName(playerid, pName, 24);
    sscanf(params, "s[128]", message)) return SendClientMessage(playerid, -1, "Usage: /irc [Message]");
    format(message, sizeof(message), "[IRC] %s: %s", pName, message);
    IRC_GroupSay(GroupID, target, message); // Change this to your own configuration (GroupID and target)
    SendClientMessage(playerid, -1, "Your message has been sent.");
    return 1;
}
